That He prohibited us from allowing an idolater that dwells in our land to work a Hebrew (Jewish) slave that sold himself, with oppressive work. And that is His, may He be exalted, saying, "he shall not rule over him oppressively before your eyes" (Leviticus 25:53). And we should not say, "Since this Hebrew slave transgressed against himself and sold himself to the idolater, let us leave him - and whatever happens, will happen; and whatever he will do to him, he will do." Rather we order this idolater about this, and prevent him from working him with oppressive work. (See Parashat Behar; Mishneh Torah, Slaves 1.)
